Book excerpt: In 2013, more than 308 million tons of cereals were produced within the European Union, of which about 60 million tons were grown as barley. The protein content of barley is rather low when compared to protein feedstuffs such as soybean meal. However, due to its high dietary inclusion level, up to half of the protein requirement of pigs can be met by barley.

This book was released on 2017-06-01 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cereal grains, such as rye and triticale are a major source of energy in pig nutrition. The crude protein (CP) content in cereal grains is rather low compared to protein ingredients such as soybean meal. However, costs and availability of soybean meal are strongly correlated with the price development of agricultural commodities on the world market. Therefore, swine producers will make increasing efforts to use protein from locally produced cereal grains more efficiently to reduce feed costs. Measurements of apparent (AID) and standardized ileal digestibility (SID) of CP and AA are frequently used to estimate the amounts of absorbable AA from the diet which are used for pigs’ metabolic processes. However, until now there is limited data on SID of CP and AA in rye and triticale, particularly in new genotypes. Therefore, one objective of the present work was to determine the variation in nutritional composition and SID of CP and AA of 8 currently available rye and 8 triticale genotypes. Standardized ileal digestibility of CP and most AA between the 8 assayed genotypes of both rye and triticale did not differ. Furthermore, average SID values of CP and AA of both rye and triticale in the present experiment were lower when compared to values of rye and triticale published in current feed tables. Thus, future research should clarify, whether these differences in comparison to feed tables are caused by experimental conditions or reflect a consistent decrease that need to be accounted for in feed tables.

This book was released on 2009-06-08 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: A cautious assessment of standardised ileal digestibilities (SID) of crude protein (CP) and amino acids (AA) as a measure to describe AA bioavailabilities is critical for evaluating the protein value of feed ingredients for piglets. Estimates of SID have been generated for most feed ingredients for grower-finisher pigs, whereas corresponding values for piglets hardly exist. Until now, SID values determined in grower-finisher pigs are used in diet formulation for piglets as well. However, there is some concern that these values may not be valid in piglets due to a limited digestive capacity for feed protein in piglets. A guideline for the standardisation of the experimental procedure in digestibility experiments had already been proposed for grower-finisher pigs. These guidelines firstly include threshold levels for CP and AA in the assay diets to obtain so-called plateau apparent ileal digestibility values, which are independent of dietary CP and AA levels, and secondly values for IAALB. For piglets, similar guidelines, including dietary threshold levels and values for IAALB, have currently been established. Therefore, the objective of the thesis was, based on these guidelines, to determine SID of CP and AA in 24 assay feed ingredients, including 11 products from soybean processing, 7 by-products from starch processing, 2 fish meals and 4 whey proteins. For this purpose, a total of 4 digestibility experiments with piglets fitted with simple T-cannulas at the distal ileum was conducted. For each experiment, 14 barrows were weaned at 18 days of age. Each experiment consisted of 3 periods for digesta collection. A total of 24 semisynthetic cornstarch-based diets with various inclusion levels of casein were formulated to which 1 of the 24 assay feed ingredients each was added. The daily feed allowance was restricted to 30 g/kg of individual body weight throughout all experimental periods. The SID values were determined by difference to SID values in casein. The results of the present studies show large variations in SID values among differently processed soybean products (p0.05). The SID values in extruded soybeans (SBe) were lower compared to high-protein soybean meal (SBMhp), soy protein concentrate (SPC) or partially hydrolysed soy protein isolate (SPIh) (p0.05). Aqueous alcohol or water extraction in SPC or SPIh improved SID values compared to SBMhp (p0.05). The SID values among the 4 batches of SPC were similar (p0.05) and consistently high. Moreover, the SID values were similar in SPC and SPIh (p0.05). The SID values of in alternatively processed soy proteins including enzymatically fermented SPA and microbially fermented SPB, were inconsistent. For the 3 SPA products, SID increased numerically from values similar to SBMhp to values similar to SPC with increasing duration of enzymatic treatment. For SPB SID values were low and similar to SBe, which may be attributed to protein denaturation during microbial fermentation. The results of present study show for most AA similar SID values for all by-products of starch processing including pea protein (PeaP), wheat gluten (WG), corn gluten (CG), and potato protein (PotP) compared to SPC (p0.05) except for SID of Lys in WG and CG, and SID of Trp in CG were considerably lower compared to other products (p0.05). The particular low SID of Lys and Trp in WG and CG might be simply a reflection of an experimental error, because SID values by means of the difference method rely on sufficient high AA contribution levels to the assay diets, which was not achieved for the aforementioned AA. The results of the present study show that SID values in fish meal (FM1) and extracted fish meal (FM2e) vary considerably (p

This book was released on 2017-05-11 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, the concept of standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) has been used in diet formulation for pigs. However, there is limited data on the nutritional composition and SID of CP and AA in home-grown European soybean and rapeseed products. For full-fat soybeans (FFSB), the presence of heat-labile trypsin inhibitors may cause problems in protein digestion of pigs. Therefore, the optimization of heat treatment for FFSB is a need to reduce trypsin inhibitor activity for improving SID of CP and AA. However, excessive heat treatment may have a negative effect on protein digestion. Furthermore, reducing dietary protein levels in combination with the supplementation of Bacillus spp. may reduce feed costs and improve pigs’ gut health. As a result of the present study, home-grown European soybean and rapeseed products can be considered as a suitable alternative to imported soybean products for pigs raised in organic and conventional farming systems. Wet heating at 100°C for 16 min, together with autoclaving at 110°C from 15 to 45 min reflects optimal heat treatment for FFSB resulting in greater SID of CP and AA with lower destruction of AA. Reducing the dietary CP level is an alternative strategy to improve SID of some AA, thereby decreasing feed cost and nitrogen excretion. The supplementation of Bacillus spp. promoted gene copy numbers of Roseburia spp., which may be beneficial due to ascribed health promoting properties of this butyrate producer.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies were conducted to evaluate the effects of corn byproducts high-protein died distillers grain (HP-DDG), and dried distillers grain with solubles (DDGS), and branched chain amino acids (BCAA) on the growth performance and meat quality of pigs. The first study evaluated the combined effect of dietary level of DDGS and HP-DDG on the growth performance of wean-finish pigs and carcass and pork quality characteristics. This study demonstrated that DDGS can be included at up to 30% in diets (without HP-DDG) without compromising growth performance of wean-to-finish pigs. However, growth performance was increasingly compromised at higher inclusion levels of both co-products and belly firmness was negatively affected by increasing levels of both DDGS and HP-DDG. A second experiment was designed to define the minimum CP level and whether non-essential amino acids become limiting in low crude protein diets for late finishing pigs. The results of this study demonstrated that late finishing pigs can be fed diets with 9.76% crude protein level supplemented with 0.32 % L-Lys HCL and other essential amino acids without affecting growth rate and that non-essential amino acids were not limiting in the low crude protein diets evaluated. A third study was designed to recreate the negative effects on growth performance of feeding diets with 30% HP-DDG inclusion level and to test if the negative effect of feeding high HP-DDG levels on growth performance can be reproduced by adding excess branched chain amino acids (leucine, isoleucine, and valine) to standard corn-soybean meal based diet. The results show that the reduction in the growth rates of growing pigs fed diets with 30% HP-DDG inclusion levels may be due to the dietary excesses of leucine present in diets with HP-DDG at 30% inclusion levels. The same effect was not present in finishing pigs. In general, growth performance and belly quality are compromised at higher inclusion levels of both HP-DDG and DDGS. The results of the last studies indicate that leucine level may play an important role on the reduction of the growth performance of pigs fed 30% HP-DDG inclusion levels.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As food and animal protein demand increases, black soldier fly larvae (BSFL) meal has gained interest in the past couple of years for use in animal feed as an alternative protein ingredient. Black soldier fly larvae is an attractive protein source; however, it is important to evaluate its amino acid (AA) digestibility and metabolic availability (MA) before incorporation in feed formulation. The global objectives of this thesis were to determine the standardized ileal digestibility (SID) coefficient of AA and MA of methionine using the indicator AA oxidation (IAAO) method from BSFL meal, and to compare the results from the two protein quality methodologies. The SID coefficient of indispensable AA in BSFL meal was found to be above 83%, while the MA of methionine was found to be 53.33%. This finding further confirms that SID coefficient tends to overestimate AA bioavailability and that MA is a more accurate representation of bioavailability.

This book was released on 2011 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three experiments were conducted to determine the AID and SID of protein and AA in pea protein isolate (PPI), distiller's dried grains with solubles derived from a blend of wheat and corn (wcDDGS) and corn. In addition, 2 experiments were conducted to estimate the requirements of digestible SAA (dSAA) and digestible lysine (dLYS) for 3-week old broilers to obtain optimum growth performance(BWG, FCR), and optimum yield performance(CY, BMY and TDY). For digestibility studies, day-old male Ross 308 broiler chicks were fed test diets from day 1-14. The test-diets were balanced for vitamins and minerals and contained chromic oxide (0.3%) as an indigestible marker. The protein and AA digestibilities were determined either by direct or indirect method. For requirement studies, day-old male Ross 308 broiler chicks were fed lysine- or SAA deficient basal diets balanced for all other AA, except for the AA under test, according to the ideal protein concept. All test diets were also balanced for vitamins and minerals and were kept isonoitrogenous and isocaloric within each assay. The average SID estimates (%) of AA were 92.4, 71.5 and 93.3 in PPI, wcDDGS and corn, respectively. Using regression analysis, the dietary dLYS requirement estimates (%) were 1.12 and 1.13 for BWG and FCR, respectively. The dietary dSAA requirement estimate was 0.81% for BWG while no significant response was observed for FCR. Both CY and BMY increased cubically with increasing levels of dLYS, whereas, CY didnot respond significantly and BMY increased linerally with the increasing levels of dSAA.
